Carson City Milkshake
When a girl lies on her back and puts her legs behind her head so she's curled up like a ball with her fa-la-la sticking up in the air. The male counterpart then squats over the girl and begins intercourse. Mid-coitus he produces the poop he's stored up from a lunch of pepperoni Hot Pockets, and shits into the girl counterparts' perfectly aligned anus.
Karen made me pepperoni Hot Pockets for lunch. You know what that means...Carson City Milkshake. *high five*
